A hose reel is an industrial tool that stores hoses by winding them around a spool. It is mainly used in scenarios such as production workshops, auto repair shops, 4S stores, and the beauty industry. It prevents hoses from tangling during use and enables free extension and retraction of hoses via a spring-driven mechanism, replacing the traditional disorganized hose management method. Its auxiliary device controls the immediate start and stop of the reel through a locking mechanism, which significantly improves work efficiency, enhances the working environment, and extends the service life of the equipment.
